Hi Anne, I discovered that this was happening because of a very stupid mistake of my own. But now a new problems have come up. I am making a .Net Client for a PDA. when I try to generate the client side proxy using the wsdl.exe available for VS.Net 2003 from the deployed web service (wsdl /namespace:HelloWorld http://craftgepc18.epfl.ch:8080/axis/services/HelloServerPort?wsdl) I get the following error:
--------------------------------------------------- Error: There was an error processing 'http://craftgepc18.epfl.ch:8080/axis/servi ces/HelloServerPort?wsdl'. - The document at the url http://craftgepc18.epfl.ch:8080/axis/services/HelloS erverPort?wsdl was not recognized as a known document type. The error message from each known type may help you fix the problem: - Report from 'WSDL Document' is 'There is an error in XML document (44, 6).'. - More than one message part named 'intElement' was specified. Each message pa rt must have a unique name. - Report from 'DISCO Document' is 'Discovery document at the URL http://craftgep c18.epfl.ch:8080/axis/services/HelloServerPort?wsdl could not be found.'. - The document format is not recognized. - Report from 'XML Schema' is 'Expected Schema root. Make sure that the root ele ment is <schema> and the namespace is 'http://www.w3.org/2001/XMLSchema' for an XSD schema or 'urn:schemas-microsoft-com:xml-data' for an XDR schema. An error o ccurred at , (2, 2).'. If you would like more help, please type "wsdl /?". ---------------------------------------------------- But if I try to generate the client side proxy from the WSDL that I wrote (wsdl /namespace:HelloWorld C:\c-sharp\helloServerWSDL\HelloServer.wsdl) it works. Using this proxy I created my client and tried calling the webservice but got the following error this time : -------------------------------------------------- InvalidOperationException Server found request content type to be 'text/html;charset=ISO-8859-1',but expected 'text/xml'. -------------------------------------------------- I had got the same error before when I tried to write the interface first and then use the java2wsdl and wsdl2java tools to build the server. I am attaching the wsdl that i wrote (HelloServer.wsdl), the wsdl generated when i view it through a browser (generated.wsdl), the proxy file generated for HelloServer.wsl (HelloServer.cs) and the client (Form1.cs). I would really be grateful if some one could help me with this.
